The City of Tempe identified manholes and collection system piping in various locations around the city that needed rehabilitation. To minimize cost and disruptions to the traveling public, pipeline rehabilitation involved the use of trenchless technologies including ultraviolet light-cured CIPP lining (UV CIPP). Manhole rehabilitation involved the use of precast manhole liner inserts and coatings.

GMP 1: The scope included 220 LF of 36" UV CIPP lining, two manhole inserts, and an 8 MGD bypass system. Work was completed quickly and safely in a limited access area while coordinating with multiple adjacent construction projects. 

GMP 2: The scope included 3,630 LF of 8" to 21” UV CIPP lining, 12 manhole inserts, four manhole rehabilitations, PVC point repairs, and an 0-1 MGD bypass system. Work was completed in many locations including major arterial intersections, minor arterial intersections, residential streets, and alleys.

GMP 3: The scope included 13 each 72” manhole insert and bench repairs.

GMP 4: The scope included 25 manhole inserts from 48” to 72”, 15 manhole rehabilitations, 1 ring and cover repair, and 3 clean/grout bench and channel repairs.
